- Scripts create json files which are then served by index.js
- Use .env to set the path to the configuration file
- Config files contains tokens, routers and other detail
- outputs in /data
- profitable arbs in merged_shortlist_XPID.json
- Use yarn to run the scripts.
- First gather token info, then pairs, then routes.
yarn tokens
- decimals.js -> data/tokens.json
- prices.js -> token_price.json
- factories.js
yarn pairs
- pairs.js -> all_pairs.json
- reserves.js -> reserves.json
- validate_pairs.js -> tradeable_pairs.json, validated_pairs.json
yarn routes
- generate.js -> routes.json
yarn simulate simulate_solid.js" -> simulation.json
merge_shortlists -> merged.json (mergedshortlists cats all shortlists in the directory)
yarn runall
decimals.js prices.js -> data/token_price.json factories.js pairs.js -> "data/all_pairs.json" reserves.js -> data/reserves.json validate_pairs.js", "data/validated_pairs.json "data/validated_pairs.json > node scripts/generate.js -> "data/generated.json simulate_solid.js
-
Replace dollar value assessment with number of tokens
-
Use obj["key3"] = "value3"; to add properties to the token and pair data objects, reduce proliferation.
-
Investigate spread operator for object merging:
let remoteJob = { ...job, ...location };
import _ as cron from 'node-cron' cron.schedule('5 _ * * * *', () => { console.log('running a task every minute at the 5th second'); });
import _ as cron from 'node-cron' cron.schedule('3 5 _ * *', () => { console.log('running a task every day at 5:03 am'); });
import _ as cron from 'node-cron' cron.schedule('0 _ * * *', () => { console.log('running a task every hour at 00'); });
https .createServer(app) .listen(4000, ()=>{ console.log('server is runing at port 4000') });
// Create an try point route for the Express app listening on port 4000. // This code tells the service to listed to any request coming to the / route. // Once the request is received, it will display a message "Hello from express server." app.get('/', (req,res)=>{ res.send("Hello from express server.") })
node index.js
- Finally, test the service by bringing up a web browser and navigating to http://localhost:4000/ in your browser. If successful, you should see a message “Hello from express server.”.
